getConfig function

Map<String, dynamic> getConfig({ String? configFile, })

Get config from pubspec.yaml or splash_screen_view.yaml

Implementation

Map<String, dynamic> getConfig({String? configFile}) {
  // if `splash_screen_view.yaml` exists use it as config file, otherwise use `pubspec.yaml`
  String filePath;
  if (configFile != null && File(configFile).existsSync()) {
    filePath = configFile;
  } else if (File('splash_screen_view.yaml').existsSync()) {
    filePath = 'splash_screen_view.yaml';
  } else {
    filePath = 'pubspec.yaml';
  }

  final Map yamlMap = loadYaml(File(filePath).readAsStringSync());

  if (!(yamlMap['splash_screen_view'] is Map)) {
    throw Exception('Your `$filePath` file does not contain a '
        '`splash_screen_view` section.');
  }

  // yamlMap has the type YamlMap, which has several unwanted side effects
  final config = <String, dynamic>{};
  for (MapEntry<dynamic, dynamic> entry
      in yamlMap['splash_screen_view'].entries) {
    if (entry.value is YamlList) {
      var list = <String>[];
      (entry.value as YamlList).forEach((dynamic value) {
        if (value is String) {
          list.add(value);
        }
      });
      config[entry.key] = list;
    } else {
      config[entry.key] = entry.value;
    }
  }
  return config;
